"Agent": Let Printing And Dyeing Wastewater To Clear Water.

April 11th, a cup of about 50 milliliters of color darkened. Industry The sewage is dripped lightly into a few drops of colorless and transparent liquid and stirred for several minutes. In less than 5 minutes, the sewage is rapidly stratified, and the floc precipitates precipitate rapidly. And this magic scientific research result is a few drops of colorless transparent liquid "Decolorizing Flocculant", also known as sewage treatment agent.

At present, the research of Henan Academy of Sciences has reached the international advanced level. Yesterday afternoon, an exclusive interview with Dong Xueliang, an Associate Research Fellow of the Henan Provincial Academy of Sciences and high tech research center, admitted that it is now a key stage for the construction of the Central Plains Economic Zone. With more and more enterprises entering Henan, the gradual promotion of this scientific research will bring positive effects and practical results.

[witness] less than 5 minutes, high chromatic sewage is clearly stratified.

Bottles, cans, various instruments, various chemicals... Yesterday afternoon, at the Provincial Academy of Sciences technology Research Center Green Chemical Laboratory, Dong Xueliang is "Decolorizing Flocculant" drip into a glass of red and a cup of brown industrial sewage, stir a few, and carefully note the change of every second...

In this way Experiment Dong Xueliang repeats thousands of times, every time, like a new start, without letting go of every slight change.

Looking at the turbidity of the sewage in the "Decolorizing Flocculant" under the action of rapid stratification, water and sediment less than 5 minutes, it has been clear.

"Success!" Dong Xueliang smiled with ease when he changed his solemn record.

"We must not be careless and careless in doing scientific research." Dong Xueliang said that every scientific research achievement has gone through the painstaking efforts of the scientific research team.

To mention this "Decolorizing Flocculant" research, Dong Xueliang is familiar with it. He said, before, ordinary sewage treatment agents can only suspend the sediment suspended in the waste water. For example, the common alum clean water used by the common people is that alum has strong adsorption capacity in the water and can adsorb impurities suspended in the water.

But for some dye factories, textile printing and dyeing factories and other high color wastewater discharged, there is nothing to do. "Can we study a new substance that can dissolve the impurities dissolved in water?" in 2005, the research team of the Henan Academy of Sciences first proposed the subject and studied it. [interpretation] "Decolorizing Flocculant" has been released for 6 years.

Since 2005, the research team has put the research into practice.

The process of experiment is boring. All day long, we must face up to bottles and cans, and we should do a lot of screening. Chemical structure, raw material structure and chemical structure of sewage treatment are clearly identified. What raw material structures should be found to deal with it?

When choosing raw materials, they should also consider the practicality and economy of raw materials. For example, Dong Xueliang said that scientific research should not only study the results, but also consider the feasibility of the application in reality. "You can't work out a product, and the raw material will be very expensive, so if you put it into use, the cost will be very high, which is not practical."

In addition to the lab, Dong Xueliang and other members of the team are constantly rushing to dye factories, textile and dyeing mills to find highly colored effluent. Red, yellow, brown, and black, and how many kinds of sewage are discharged, they have to do thousands of experiments on this basis.

After nearly 6 years of research, the next step is to put this research achievement into scale production and industrialization stage and apply it to practice. [harvest]

Henan has reached the international advanced level.

Dong Xueliang said that the successful launch of the scientific research marks that Henan has reached the international advanced level in related scientific research achievements. And their green chemical laboratory, in the research focus on two aspects, one is the use of green technology to create, to minimize resources and energy consumption, reduce the use of organic solvents and three wastes (waste water, waste residue, waste gas); two, products throughout the life cycle are green, environmentally friendly, reduce environmental pollution.

The success of "Decolorizing Flocculant" also confirms these two aspects. The sediments can be burned or recycled as raw materials, and reclaimed water can also be used.

According to introducing, although the water can not be directly consumed, but in many aspects of daily life can replace tap water, save precious water resources. It is understood that in the United States, Japan, Britain, Germany and other developed countries, reclaimed water has been widely used. Lavatory washing, garden and farmland irrigation, road cleaning, car washing, city fountains, fire fighting, enterprise equipment cooling and so on are all used "reclaimed water".

Dong Xueliang said that in recent years, the application of "reclaimed water" in China has gradually shown results. 70% of the water supply from the "bird's nest" comes from reclaimed water. The greening of the venues and the washing of the runway come from reclaimed water. Even the lake in the Olympic Games is mostly reclaimed water.

With the application of "Decolorizing Flocculant" in reality, it is foreseeable that it will bring more environmentally-friendly, low-carbon, green and healthy environment to residents.
